  • I got this working in the end by changing my functions php to:

    // Make sure featured images are enabled
    add_theme_support( 'post-thumbnails' );
    // Add featured image sizes
    add_image_size( 'home_portrait', 1000, 1000, false ); // width, height, crop
    // Register the three useful image sizes for use in Add Media modal
    add_filter( 'image_size_names_choose', 'wpshout_custom_sizes' );
    function wpshout_custom_sizes( $sizes ) {
    	return array_merge( $sizes, array(
    		'home_portrait' => __( 'Home Portrait' ),
    	) );

    Though I am still unsure why the initial code did not work
